Liebe Kolleginnen und Kollegen,

soeben erreichte uns nachfolgendes RedHat Security Advisory. Wir geben
diese Informationen unveraendert an Sie weiter.

CVE-2011-2464 - Schwachstelle in ISC BIND 9

  Durch eine Schwachstelle bei der Verarbeitung von UPDATE-Anfragen in
  BIND Version 9 ist es moeglich, den Dienst zum Absturz zu bringen. Dies
  betrifft sowohl rekursive, als auch autoritative Server. Ein entfernter
  Angreifer kann dies ausnutzen, um mittels eines speziell praeparierten
  Pakets, dass direkt an den Server gesendet wird, einen Denial of
  Service-Angriff durchzufuehren.


Betroffen sind die folgenden Software Pakete und Plattformen:

  Paket bind

  RHEL Desktop Workstation (v. 5 client) - i386, x86_64
  Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x,
  x86_64
  Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64
  Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64
  Red Hat Enterprise Linux HPC Node (v. 6) - x86_64
  Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64
  Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64
  Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x,
  x86_64
  Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64
  Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64


Vom Hersteller werden ueberarbeitete Pakete zur Verfuegung gestellt.

3. Description:

The Berkeley Internet Name Domain (BIND) is an implementation of the Domain
Name System (DNS) protocols. BIND includes a DNS server (named); a resolver
library (routines for applications to use when interfacing with DNS); and
tools for verifying that the DNS server is operating correctly.

A flaw was discovered in the way BIND handled certain DNS requests. A
remote attacker could use this flaw to send a specially-crafted DNS request
packet to BIND, causing it to exit unexpectedly due to a failed assertion.
(CVE-2011-2464)

Users of bind97 on Red Hat Enterprise Linux 5, and bind on Red Hat
Enterprise Linux 6, are advised to upgrade to these updated packages, which
resolve this issue. After installing the update, the BIND daemon (named)
will be restarted automatically.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

718966 - CVE-2011-2464 bind: Specially constructed packet will cause named to exit
